About this route:
A direct, nonstop flight between Waterfall Seaplane Base (KWF), Waterfall, Alaska, United States and Challis Airport (CHL), Challis, Idaho, United States would travel a Great Circle distance of 1,121 miles (or 1,803 kilometers).
A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the relatively short distance between Waterfall Seaplane Base and Challis Airport, the route shown on this map most likely still appears to be a straight line.

- Waterfall Seaplane Base (KWF) currently has only 1 runway.
- The closest airport to Waterfall Seaplane Base (KWF) is Craig Seaplane Base (CGA), which is located only 13 miles (21 kilometers) NNE of KWF.
- Because of Waterfall Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Waterfall Seaplane Base at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
- The furthest airport from Waterfall Seaplane Base (KWF) is Port Alfred Airport (AFD), which is located 10,657 miles (17,150 kilometers) away in Port Alfred, South Africa.
Facts about Challis Airport (CHL):

- In addition to being known as "Challis Airport", another name for CHL is "LLJ".
